✦ Synopsis
A series of a-hydroxy oxlme compounds was synthesized and characterized A new type of adsorbent, cellulose trlacetate (TAC) powder (20-60 mesh) contammg five hnds of ry-oxnne compounds such as a-benzom ome and 2-hydroxyphenyl ethyl ketone oxlme (HPEKO), was prepared by dlssolvmg cellulose trracetate with a-oxlme m dlchloromethane and pourmg the murture mto hot water The adsorptIon behavlour with a-oxlme-TAC powders was exammed for seven metal Ions from solution of pH 2-10 Copper(M) was quantitatively retamed on the HPEKO-TAC m the pH range 4-10 m batch expenments, whereas neghglble adsorptIon was obtained for cobalt(M), Iron(II1) and Iron( palladmm(II) was also quantitatively adsorbed The retention capacity of coppel(I1) and mckel(II) on the loaded adsorbent was about 14 and 11 mg g-' at pH 5 9 and 8 1, respectively Copper retamed on the column was completely eluted wth 50 cm3 of 0 25 mol dmm3 hydrochloric acid, and separated from mckel(II) and Iron(II1)
